What is AB testing for dummies?
A/B/n tests are controlled experiments that run one or more variations against the original page. Results compare conversion rates among the variations based on a single change. Each element has a specific impact and use case to help you get the most out of your site.
How AB testing is done?
How A/B testing works. In an A/B test, you take a webpage or app screen and modify it to create a second version of the same page. This change can be as simple as a single headline, button or be a complete redesign of the page.
How is oil contamination determined in an abrasive test?
Oil contamination is determined in accordance with ASTM D7393, Standard Practice for Indicating Oil in Abrasives. This field test, commonly known as the vial test, requires that a sample of abrasive be placed in a clean, sealable container. Tap water is added to the container so that it is approximately 1 inch above the abrasive.
Can a laboratory test the cleanliness of an abrasive?
Abrasive manufacturers may have performed laboratory analysis of the product, but this does not satisfy the requirements of SSPC abrasive standards. More importantly, it does not reveal the current condition of the abrasive. Transporting, storing, and recycling of the media can affect the cleanliness of the abrasive.

Is there a way to tell if a fuel sample is contaminated?
The tests we perform on contaminated fuel generally give yes or no answers to specific questions; there is no one ‘contamination’ test that can both confirm that a fuel sample is contaminated and identify the source of contamination. The best way to test contaminated fuel is to start with the most likely source of contamination and go from there.
